Problems solved by technology
[0006] The prior art solution needs to reconfigure the radio frequency module, the clock generation device, and the digital intermediate frequency processing module, so that when switching between system modes, the switching process is relatively simple. Long, resulting in a long processing time, affecting the efficiency of production line testing
And during the switching process, it is necessary to reload the simulator running program, which increases the processing complexity and risks loading failure, which affects the basic business continuity in multi-mode system testing

The invention discloses a mode switching method of multi-mode mobile terminal test equipment and an apparatus thereof, wherein, a radio frequency module converts a radio frequency signal of a detected terminal into an analog intermediate frequency signal; a digital analog conversion module converts the analog intermediate frequency signal into a digital intermediate frequency signal; a digital intermediate frequency processing module carries out processing on the digital intermediate frequency signal to obtain base-band digital signals of rates corresponding to different communication modes and respectively outputs the base-band digital signals to corresponding signaling processing modules; the signaling processing modules carry out uplink channel demodulation and protocol processing on the signals outputted by the digital intermediate frequency processing module, and according to a communication mode switching command, when a target communication mode is a communication mode corresponding to a present module, output a downlink channel modulation signal processed by the present module to the digital intermediate frequency processing module; according to an uplink signal outputted by the digital intermediate frequency processing module, and according to a given measurement type, the measuring module carries out uplink signal measurement. By employing the method and the apparatus in the invention, system mode switching efficiency is raised.
Description
technical field [0001] The invention relates to mobile communication terminal testing technology in the field of communication technology, in particular to a mode switching method and device for multi-mode mobile terminal testing equipment. Background technique [0002] Compared with the 2G GSM (Global System for Mobile Communications, global mobile communication) system and other wireless communication systems, the third generation mobile communication system (3G) has large user capacity, wide coverage, suitable for uplink and downlink asymmetric services, It has the advantages of high spectrum utilization, low equipment cost, and abundant system frequency resources. At present, with the continuous advancement of the large-scale commercialization of TD-SCDMA (Time-Division Synchronization Code Division-Multiple-Access, Time-Division Synchronization Code Division Multiple Access), domestic dual-mode terminals have been mass-produced and applied. [0003] In the terminal pro...
